[Mimedefang] SA network tests with MIMEDefang 2.53

[Rikard.Elofsson at ninetechgruppen.se]

Hi!

I'm using MIMEDefang 2.45 with SA 3.1.0 and everything, including Razor,
Pyzor, DCC, DSNBL etc works as it should. When I upgrade MIMEDefang to 2.53
all network tests seems to stop. No spam is marked with the network tests
and nothing is logged in the Razor log.

I use the same config files etc, just switch version of MIMEDefang. I can't
find anything in the documentation or changelog to explain this, does
anyone know why this is happening?

Regards
